This invention relates to new and useful improvements in a crude 011 burner.

The invention has'for an 'ob ect the provision of a device vof the class mentioned which isof simple, durable constrhctiomdependable plugged'at one end and threaded at the diametrically opposite end for connection with a steam pipe, a nozzle engaged in one ofthe remaining ends of said fitting, an atomizer pipe support engaged in the other end and adapted for connection with a fuel supply, an atomizerpipe supported in said support, and means for holding the said atomizer pipe in various adjusted positions relative to the The invention also proposes means for locating the position of such atomizer pipe-from the exterior of the burner.

- This construction: presents various advantages, one being that the'adjustment of the atomizer pipe is-internal to the'burner, Further, it is a'very simple apparatus without complications in its-system of atomization, and is adapted to any boiler that burns crude oil under pressure of steam, whether stationtubes for conducting. the steam and the crude oil are independent from one another so that no clogging can occur. The atomizing system of the burner burns the crude oil immediately as iticomes out of 5. the nozzle produclng a column of. firefrom four to siX meters in circumferentiallength WlljllOIlt. materlal expansion. The flame is white and not red as with common burners,

and it is especially adapted for railroad boil- -.ers. It does not produce any smoke, and if any, of a very insignificant density which shows that complete atomization of the crude oil takes place andthereforea considerable economy of fuel in comparison with common boilers generallyused... It is extremelyuseful for boilers that have to maintain a constant high pressure due todensity of the heat thatitproduces. V i 1 This boiler also has various advantages to be cleaned every two to four hours, not eve-n ary, portable or of the marine type. The p. l description and accompanylng drawings,-and

the production'of high heat, the system of 1 atomizing crude oil under steam pressurefa complete atomization of the crude oil,jnonclogging as sand or other particles of foreign matter deposited in the fuel tanks, does not require high pressure pumping as all other burners used at the present time.

A further-advantage is that it does not need when the oil is dirty, as once the burner is 0 adjusted to the boiler and the fire regulated it will not have to be removed as it will not require cleaning owing to the fact that the blowing of the steam will sweep out all that may be inside once'the conduit of the crude oil is closed, as that is taken out from the vacuum, does not form carbon in the form of a cone'as do many present burners that are in use, which interferesvvith the flame, no residue is left in'thefire pit because all the crude oil is completely burned as it passes, and produces no smoke, uniformity of heat keeps the steam pressure alwaysjuniformly maintained, and -it'has-g'reat economy of fuel,since to the appended claims in which the various novel features of the invention are more particularly set forth;

The crude oil burner consists of a cross pipe fitting 10 plugged at one end 11 andthreaded at the diametrically opposite end 12for connection with a steam pipe, a nozzle 13 engaged in one of the remaining ends of the fitting, namely end 14E, an atomizer pipe support 15 engaged in the other end 16 and adapted for connection with a fuel supply, an atomizer pipe '17 supported on said support 15, and means for holding said atomizer pipe in various adjusted positions relative to the nozzle13.

p The three open ends of the cross pipe fitting are formed withpipe threads. The inner end of. the nozzlel is threaded for engaging the pipe threads of the fitting and is formed with a shoulder-L18 for abuttingagainst the outer face of the fitting. The atomizer pipe support 15 is also formed with pipe threads engaging the threads in the open end 16 of the cross pipe fitting and is formed with a flange 19 abutting against the outer surface of the end. The atomizer pipe support 15 is also formed with a hexagonal portion 20 for receiving a wrench or other turning tool so that it may be tightly engaged in place. Indicating arrows 21 show the path of the steam, and indicating arrow 22 the path of the crude oil. The nozzle 13 has an inner converging passage 23 connected with an outer flaredportion 24. j

The atomizer pipe support 15 is also provided with a pair of spaced laterallugs 25 for receiving a supporting pin from a control system not shown on the drawings. The inner end of the atomizer pipe 17 is threaded with screw threads and engaged in a threaded aperture extending thru the inner end of the atomizer pipe support 15. The means for holding said atomizer pipe 17 in various adjusted positions relative to the nozzle 18, consists of a nut 27 engaged upon the threads of the pipe 17 and abutting against the pipe support 15.

In the modified form of the device illustrated in Figs. 5 to 7 inclusive, a means has been shown for holding said atomizer pipe 17 in various adjusted positions relative to the nozzle and consists in longitudinal-ribs 28 formed upon the atomizer pipe and engaging thru grooves in the pipe support 15 so as to be slidable. The inner end of the pipe 17 is formed with a piston portion 28 encircled by a packing bushing 29 arranged to be a tight fit within the pipe. support 15. The inner end of the'piston portion'28 is flared as indicated by reference numeral 30. One of the ribs 28 is formed with rack teeth 31 engaged by a gear 32 fixed upon a spindle 33 tended or retracted positions. .49 and 40 do notextend thru the atomizer pipes but are only arranged slightly into its the new position,

rotatively extending thru the pipe fitting 10. A hand wheel 34 is fixed upon the outer end of the spindle 33 for manual operation to cause the atomizer pipe 17 to assume various adjusted positions. 7

In the modified form of the device illustrated in Figs. 9 and 10, a means has been disclosed forlocating the position of the said atomizer pipe from the exterior of the burner and consists of a plurality of plungers 35 ar: ranged in a longitudinal row upon the nozzle 13 and extending into the interior. Each of these plungers consists of a stem 36 slidably engaged thru the nozzle, a head 37 on the exterior of the stem, a cross pin 38 thru thestem and within the nozzle, andan expansion spring 39 acting between the nozzle and the head 37 for normally urging the stem outwards. The atomizer pipe 17 is formed with a small longitudinal slot 40 of limited length so that one of the plungers 35 may be depressed for engagingwithin the slot and abutting against one or the other ends as the atomizer pipe is adjusted and so limit its Ipositionfrom the exterior. If one of the other plungers is depressed, a different set of limiting positions is obtained.

In Fig. 8, another means has been shown for locating the position of the atomizer plpe 17 from the exterior of the burner, and purticularly for use with the form of the device illustrated in Figs. 1 to 4; inclusive. This means-consists of the plungers 35 similar to those previouly described, but engageable in a spiral slot 40' formed in the atomizer pipe 15 so that the atomizer-pipe may be rotated to various adjusted positions and the 'depressed plunger engaged against one of the ends of the spiral slot and thus limit its ex- The slots surface. a

This burner is adapted to use oil known under the name of asphalt. It is adapted to atomize the asphalt oil and produce more of the combustible gas, therefore it is moreeconomical in use. It does not consist of many parts so that'it may easily be dismounted if.

it is necessary. The burner may be formed of various sizes for adaptation to any boiler no matter of what design. The nut 27 may be loosened and the atomizer pipe 17 adjusted relative to the nozzle 13, and then the nut 27 tightened back into its place for maintaining In the form shown in Figs. 5 to 7, the hand wheel 34 maybe rotated for accomplishing the adjustment of the atomizer pipe.
